I believe that the ctypes module makes sense here, because you're essentially asking how to perform low-level bit casting. Your question is basically, how do I tell Python to take some data and interpret that data as if those exact same bits were a different data type?

In C if you had an int and wanted to interpret its bits as a float, you'd do roughly the same thing, taking a pointer and then casting and dereferencing it:

int i = 0x41973333;
float f = *((float*)&i);

and that's exactly what the Python code using the ctypes library is doing in my example.
